Filament Monitor Data Access from OM

[Diamondback]

Hey,

would it be possible to expose some more data of the Magnetic Filament Monitors in the obejct model?
I'm specifically thinking about this the new custom graph feature of the BtnCmd plugin to create a graph of the filament throughput measurements.

Not only does this look nice, it might also be helpful in debugging some things.

@Diamondback what data are you looking for?

[Diamondback]

@dc42 Sorry, looks like I expressed myself badly
It would be cool if the instantaneous "movement reading/percentage" (ie the thing that is checked against the percentage thresholds from the R parameter) would be exposed, I assume you have that value somewhere?
This way we could make a nice graph of how that value behaves over time.

@Diamondback to avoid excessive utilisation of the CAN bus, I will need to limit the update rate to around one sample per second.

[Diamondback]

@dc42 That sounds like a more than high enough update rate, I'd probably be happy with even slower rates, but if you think once per second is good, that's perfectly fine

[Diamondback]

@dc42 Thinking of something like that in the end for BtnCmd:

If the sensor data was exposed in OM, the chart would be functional

@Diamondback This is one of the features i would really love.

@dc42 Maybe I can bring this idea back up since you are currently working on the filament monitors anyway?

@dc42 Thanks for adding this in 3.5 rc2 Very useful
(The sensor here is almost 1m away from the extruder, so in case the signal looks too noisy, that's why)
